Bieleboh (Upper Sorbian: Běłobóh) is a mountain in the Lusatian Highlands, in the east of Saxony, Germany.

Bieleboh is located between the villages of Beiersdorf and Cunewalde, on the border of districts Bautzen and Görlitz which passes about 60 m north of its summit.

In 1746, Bieleboh was still called Hoher Wald, and only on maps printed between 1780 and 1806 it was first named as Pilobogg or Beyersdorferberg, together with Zschernebog (Czorneboh).

In 1841, Karl Benjamin Preusker (1786–1871), a librarian and archaeologist from Löbau, made drawings of a legendary rock formation on the summit which he called "the altar of Bielybog".

[3][5] Local historians from Sohland an der Spree examined this presumed altar for its possible calendarial use for observations of the sun in 2007.

It could be shown that an eye-shaped opening through the rock, the Teufelsauge ("devil's eye"), allows to determine the day of the equinox when the light of the rising sun passes through it.
